EDWARD Nanna, or san raeivcrsoo.' cai-mesma GAS HEATER.

Application led March 22,. 1927. Serial No. 177,328.

My invention relates to improvements in heaters arranged to be set over a 'burner or .a gas plate or thelike for heating a-room.

The primary object of the present invention is yto provide" an improved heater which may be removably placed over a gas burner to provide a large heatradiating area whereby a room may be quickly and economically heated. y.

A further object is to provide an improved device of .the character described `arranged to insure a complete-combustion of thegas before the products of combustion pass from the heater into the room.

Another object is to provide an improved construction which can be economically manufactured, and which will be neat and attractive in its appearance.

A still further object is to provide, as a 20 new article of manufacture, an improved heating device which can be readily placed over any convenient gas burner to obtain a quick or temporary heating of a room.

I accomplish these and other objects by means of the improved device disclosed in the drawings forming a part of the present application wherein like characters ot ref'- erences are used to designate similar parts throughout the specication and drawings, and in which, v

Fig. 1 is a vertical section through my im provedheater, and Fig. 2 is a broken plan View of the heater, portions` being broken away and shown in section to illustrate the construction and arrangement. n

Referring to the drawings, my improved heater will be seen to consist of an outer shell 1, having converging sides and closed across the top by means of a top plate 2. A plurality of openings 3 are formed in the lower portions of the sides of the shell 1.'

A bottom member 4 is secured within the bottom of the shell 1, said member 4 being provided with a tlanged'edge 6 arranged to 46 nest within the bottom edge of the shell 1y and to'hold the bottom member in spaced relation to said bottom edge. A plurality of openings 7 are formed in the bottom member 4. f

An inner shell 8 is secured upon the upper side of the bottom member 4, said shell converging upwardly. The shell 8 is' closed across the top and has a plurality of open ings 9 formed around the sides. A ange 11 is preferably formed upon the lower'edge phere.

of the shell 8 whereby ysaid shell may be secured upon the bottom member 4.

A bathe member 12 is mounted within the heater between the outer and inner shells 1 Yand 8, respectively, said member 12 having its sides converging to form a relatively small opening at the top slightly below the top plate V2. v yThe lower edge of the member 12 isl 'nested between the shell 1 andthe ange 6. y

@A frame 14 kisitted around the lower edge of the shell 1 said member preferably being cast and provided with a flange 16 to which the shell 1, the member 12, and the flange 6 are firmly clamped in proximate relation by Vmeans of suitable securing members 17.

Vwhereby the heater may be lifted and moved.

ln operation, the heater is placedy above any suitable burner not shown, as the burners of a gas plate or gas stove. The 'flame from such burner is directed against the raised bottom portion 4, and the products Y of combustion pass through the openings 7 and into the inner shell 8. From the inner shell, the products ot combustion, and air drawn upwardly therewith, pass through the openings 9 and thence upwardly through the open upper end of the battle member12. The air and combustion gas must then descend around the outside of the member 12 and pass outwardly through the openings 3. This causes the gas and air to follow a tortuous path whereby a complete combustion is caused before the products passk outwardly from the heater into the room. At the same time, the gas and air passing through the heater are retained for suilicient time to insure a thorough drying of the air and gas. This prevents the esca-pe of objectionable fumes into'theroom and insures a dry atmos- The bottom member 4 and the inner shell 8 are heated to a very high degree, and heat is transmitted to the baffle and to the outer shell, thereby obtaining a relatively large area from which the heat may radiate, and at the same time, the outer shell is protected from the extreme heat present directly over the heater, thereby permitting a neat and attractive appearance to be maintained.

ing a room quickly, as in the early morning before an apartment has been heated. The device is also useful for the temporary heating of an apart-ment, as when av regular source of heat has been turned olf or is inoperative. The large heating area and the complete combustion and drying of the fuel permits it to be used over any open burner to obtain a rapid heating of the room with only a small consumption of fuel.

Having thus described my invention'what I claim as new and desire to secure by Letters Patent is, f

l. An article of manufacture, a gas heater comprising an outer shell closed at its upper end and having openings formed around the lower portion of its sides; a baille member nested within the outer shell and open at the top thereof; and an apertured bottom shell nested within the baffle member to protect said outer shell and baiile from direct exposure to a burner below the apertured The device is particularly useful for heatc bottom shell.

2. An article of manufacture, a gas heater 'comprising anouter shell closed at its upper end and having openings formed around the lower portion of its sid'es; a` baille member nested within the outer shell and open at the top thereof; and an apertured bottom shell nested within the baille member to protect said outer shell and baffle from direct eX- posure to a burner below the apertured bottom shell; and an apertured inner shell having a closed top and mounted upon the bottom member to diffuse heat Within the baie member.

Inv witness whereof I hereunto set my signature.
